RATCHET-HANDLE FOR CAR-BRAKES.

SPECIFICATION forming-part of Letters Patent No. 459,101, datedSeptember 8, 1891.

y Application filed October 30,1890. Serial No. 369,817. (No model.)

T @ZZ whom, it may concern.:

Be it known that I, MORITZ VEBER, of the city of St. Louis, in the Stateof Missouri, have invented a certain new and usefulImprovementiuRatchet-HandlesforCar-Brakes,

of which the following is a full, clear, and exact description,reference being had to the accompanying drawings, forming part of thisspecification.

1o My invention relates to an improved ratchethandle for car-brakes,intended more particularly for use on street-cars; and my inventionconsists in features of novelty hereinafter fully described, and pointedoutI in the claims.

I5 Figure I is a side elevation of my improved handle. Fig. II is anenlarged detail vertical section taken on line II II, Fig. IV. Fig. IIIis a similar vieW taken on line III III, Fig. IV. Fig. IV is atransverse section taken on zo line IV IV, Fig. II. Fig. V is atransverse section of the socket part of the handle and a top view ofthe brake-rod and the pawls or dogs.- This figure is a modification ofthe form shown in Figs. II, III, and IV.

Referring to the drawings, 1 represents the upper end of the brake-rod,and2 the handle, having a lower end 3, formed with a recess or socket 4,to receive the upper end of the brake-rod. The eXtreme upper end of the3o rod is formed with a reduced portion or neck 5, fitting in anextension 6 of the socket or opening 4. The neck 5 has an annular groove7, in which fits the inner end of a plug S, which passes through thehandle and serves to connect the handle to the brake-rod, While notinterfering with the turning of the handle upon the rod. Beneath theneck the rod is provided with one or more vertical grooves 9, in each ofwhich is placed a dog or pawl 10, made preferably of steel. I have showntwo grooves, but one or more may be used.

The dogs or pawls are forced outward by means of suitable springs 11.Coil-springs are preferably used and are fitted or placed in openings12, formed in the rod, as shown clearly in Figs. III and IV. Each pawlor dog has on its outer surface an acute angle or corner 13 and arounded corner 14. The interior of the part 3 of the handle is formed 5owith grooves 15, having rounded corners 1G and acute shoulders 17,constituting a ratchet. These grooves may be formed inthe metal of whichthe handle is composed, as shown in Fig. V, or they may be formed in aseparate bushing or collar 18, placed within the part 3 of the handle,as shown in Figs. II, III, and IV. I prefer to form them in a separatebushing, for the reason that they can be readily renewed when theybecome Worn.

IVhen the brakes are to be applied, the han- 6o dle is turned in thedirection of the arrow, Fig. IV, and the turning' of the handle willcause the brake-rod to be turned, because the acute corners 13 of thedogs or pawls are held by the springs 11 into engagement with the 65shoulders 17. NVhen the handle is turned in` the opposite direction, therod is not turned, because the dogs or pawls are thrust inward `againstthe pressure of the springs 11 by the rounded corners 16 of the grooves15 bearing 7o against the rounded corners le of the dogs or pawls, andthus the brake-rod can be turned forward by the handle Without making acomplete revolution cf the latter, the advantages of which are wellunderstood.

A construction of this kind is strong, cheap, and durable, and is notliable to get out of order.

I claim as my invention- 1. In a ratchet-handle for car-brakes, the 8ocombination of the brake-rod having longitudinal grooves, springactuatedpawls or dogs fitting in said grooves, and a handlehavingasocketprovided withlongitudinalgrooves adapted to receive saidpawls or dogs, substantially as and for the purpose set forth.

2. In a ratchet-handle for car-brakes, the combination 'of the brake-rodhaving longitudinal grooves, spring-actuated pawls or dogs fitting insaid grooves and having, respect- 9o ively, acute corners 13 and roundedcorners 14, and a handle having grooves formed With acute shoulders 17and rounded corners 16, substantially as and for the purpose set forth.

3. In a ratchet-handle for car-brakes, the 9 5 combination of thebrake-rod having longitudinal grooves and transverse openings, dogs orpawls fitting in said grooves and coilsprings fitting in said openings,a handle, and a bushing fitting in va socket of the handle roo andhaving grooves to receive said pawls or with pawl lugs or dogs capableofoperation dogs, Substantially as and for the'purpose set inconjunction with the ratchet' .teeth or ro forth. v v grooves, allsubstantially as described. 4. A brake-handle having its hase recessed 5or socketed and formed with ratchet teeth or MORITZ TEBER grooves, incombination with the upper end In presence of A A of the brake-shaft,adapted to enter said THOS. KNIGHT,

socket in the base of lthe handle and provided A. M. EBERSOLE.
